Hi!

I have some problems with my friend Sebastaino (he is a boy, but we don't stay together, we are just friends) and I don't know what to do!
We have known each other since he was 4 months and I was 8 months.
When we were 9 he moved to a small town called Bra in another region and since he moved, I've visited him lots of times while he came to Milan very few times.
Last september he asked me to spend a week there but I said I couldn't because I wanted to spend some times with my old middle school friends because I wouldn't have seen many of them often as we all moved to high school.
When I told him, he got angry and told me that if we are friends I have to show him that I really care about him.
I told him that I've always visited him and that I would have gone to Bra during the Christmas holidays.
After that, we haven't talked until december when I wrote him a message where I apologized and told him that I really care about our friendship and that everything which is already happens can be changed and so he should forgive me
He answered me that I was right and everything returned as it was before. (I thought it was..)
We didn't meet at Christmas because he visited his grandma in Austria.
He called me 2 weeks ago and he seemed cold and.. well.. he was strange.
It was like he was still angry with me.
I couldn't talk with him much because I was out with a friend..
Do you think he is still angry with me? If he is, what should I do to make everything return like it was before?
Please I really need your help!
Thank you! xx
